Sixty-seven people from 36 countries were sworn in at Friday's ceremony.
Among them was 102-year-old Yun Chang. He moved from Korea ten years ago to join his family in Montgomery County including his son-in-law Chung Yeom.
"As of today, all of my family including his mine, siblings, citizens of the United States. Very exciting," said Yeom.
At 102-years-old Chang is not the oldest individual to take the Oath. Officials say centenarians sworn-in have ranged in age from 100 to 117 years old.
It was an exciting day for all in attendance - a day filled with new hopes and dreams.
"I'm so excited, I'm a new USA citizen," said Jose Guanbayro.
For the Dominican Republic native, becoming a United States citizen means he can join the Army.
For Claudia Mancanarez of Honduras, it means something different.
"Pride…and hope," she said.
Some explain they're becoming citizens because their already children are. Others hope for new beginnings.
"First thing I'm planning to do is bring my wife and kids here and start a new life in the United States," said Modesto Matias.
